摘要:
An electrophoretic coatable sealant composition for use in assembling automobile bodies comprising an adhesive material selected from the group consisting of epoxys, urethanes, epoxyurethane hybrids, acrylics, epoxy-acrylic hybrids, polyvinylchlorides and mixtures thereof and a conductive filler in an amount such that the sealant composition will accept electrophoretic deposition of a primer composition yet preserve the adhesive properties of the sealant composition. The conductive filler is selected from the group consisting of non-treated furnace-type conductive carbon blacks.
摘要:
Thermally stable hot applied plastisol compositions are especially useful in the assembly of metal parts. The compositions have adhesive and sealant qualities which allow them to be used in automotive assembly plants. Compositions of the invention comprise as major ingredients finely divided polyvinyl chloride resin, plasticizer, thermoplastic polymeric resin which is solid at room temperature but softens to a flowable state at application temperature, and an adhesion promotion system. Optionally a filler, wax, heat stabilizer, pigment, wetting agent, or mixtures thereof may be added. The individual components work synergistically to get good application properties, metal adhesion, wash-out resistance, and paintability.
摘要:
A method for making a filler from automotive paint sludge is provided. Paint sludge containing water, solvent and uncured polymer resin is treated by removing a first portion of the water by mechanically drying the sludge to produce a concentrated sludge, and a second portion of the water is removed by treating the sludge with a chemical drying agent to produce a dried powder. Alternatively, the second portion of the water may be removed by agitating the concentrated sludge under a vacuum to produce a dehydrated putty. The resulting dried powder or putty can then be used as a filler in sealants and other products.
